Why is it difficult to put a football under water than a table tennis ball?
Water is denser than air, so it requires more force to move an object through it. A football is larger and has a greater surface area than a table tennis ball, so it experiences more water resistance when submerged. Additionally, the air inside a football is compressed when it is submerged, which further increases the force required to keep it under water.
The shape of a football also contributes to the difficulty in submerging it. The curved surface of a football creates a pocket of air that resists water penetration. In contrast, the flat surface of a table tennis ball allows water to flow over it more easily.
As a result of these factors, it is significantly more difficult to keep a football submerged under water than a table tennis ball.
